Alternatively, the owner's mobile terminal is acquired by a friend and viewed in an application, which may result in personal privacy disclosure or embarrassment, for example, an incumbent heterogeneous friend of the owner may undoubtedly browse pictures, chat records, communication records, logos, etc. of a former heterogeneous friend of the owner, resulting in a total dilemma of the owner. As another example, the non-owner may browse other user information in the owner's mobile terminal, such as names, work units, phone numbers, emails, and communication records of friends and relatives, so that the information can be used to impersonate the owner, sell personal information, or perform precise marketing, which may have a negative reputation or adverse effect on the owner. Therefore, there is a need for information setting and scientific management of electronic devices, so as to better protect the information security of owners and avoid the leakage of personal information, privacy information, friend and friend information and contact data. However, in the prior art, the screen is often locked for the electronic device, so that the electronic device is unlocked by inputting a password, inputting biometric information, inputting a gesture and sliding or generating a pattern, and the security level is not high, for example, a non-owner may try to input the password continuously, or infer an unlocking password according to a scratch on the screen of the electronic device, or obtain the fingerprint of the owner by an illegal means and then unlock the electronic device by manufacturing a fingerprint mold through reverse engineering; in addition, even after unlocking, information in the electronic device cannot be classified or set, so that a non-owner sees contents which cannot be seen; in addition, if the electronic equipment is lost once, the electronic equipment is often difficult to return, so the prior art lacks relevant measures on the return of the lost electronic equipment and the leakage prevention guarantee of the content of the lost electronic equipment.

Then the transformation module converts the selected information into a picture format in a screenshot mode and executes the following operations: calculating pixels of the picture to obtain u × v pixels, dividing the picture into P image tiles (tiles) which are not overlapped with each other, arranging pixel values of the image tiles in sequence from few to many to obtain a sequence tile1, tile2, … … and tile of the image tiles, and taking a middle value in the sequence to obtain a median image tile of the sequence, wherein when w is an even number, an image tile with a sequence number of half of a w value is taken as a median image tile, and when w is an odd number, an image tile with a sequence number of an integer part of half of the w value is taken as a median image tile; calculating w-1 number differences of pixels of the median image tile and other image tiles in the sequence; the difference in the number of pixels of the median image tile and each image tile is then modified to generate an offset: wherein the difference in the number of pixels of the median image tile and the image tile is incremented by one when the difference in the number is greater than an eighth threshold which is a positive integer, and decremented by one when the difference in the number is less than the inverse of the eighth threshold which is a positive integer, and the difference in the number of pixels of the median image tile and the image tile is unchanged when the difference in the number is between the eighth threshold and its inverse, including between the two endpoints; and then traversing the number difference of each corresponding pixel in the image tiles, modifying the offset generated according to the number difference of the pixels of the median image tile and each image tile, inserting a binary password bit into a vacancy formed by the offset, and inserting an offset identifier between the image tiles, thereby realizing format conversion of the content to be stored for peeping prevention and leakage prevention, further storing the content into a specified area of the electronic equipment, and displaying an icon above a screen to prompt that the content stored for peeping prevention and leakage prevention exists when the context information of the content is displayed.
In the process that information from one position to another position is selected, the pressure sensor judges the selected position, when effective pressure is detected to stay at one position on the touch screen, a trigger signal is sent to the timing module and timing is started, when the pressure range is detected to move, timing is stopped, and the same operation is executed at another position; a selected procedure that is considered valid only if the timer determines that the time period at both locations exceeds a predetermined requirement; wherein the step of determining to make a selection at a location is: dividing the information of the application program into different parts according to a preset unit (for example, according to each chat record, each short message and each picture), taking a center line between the part and the previous part as an upper boundary of the part, taking a center line between the part and the next part as a lower boundary of the part, and taking the upper boundary, the lower boundary and a rectangular area between the left side and the right side of the screen as an area of the part; when the user touches with a finger, the pressure sensor firstly judges an effective touch range with a pressure value meeting the requirement, calculates the number of pixels of the effective touch range in different parts and the proportion thereof, determines a part as a selected part when the effective touch range is completely positioned in the part, determines a part with the proportion more than half as the selected part when the effective touch range crosses a midline touch, prompts the user to reselect on a screen when the effective touch range crosses the midline touch range, and repeatedly executes the above operations to determine the selected part.
According to an exemplary embodiment of the present invention, the cryptographic transformation comprises the steps of: the user stays a finger at a certain position (such as a chat record, short message information and a picture) in the application program for a certain time in a window presented by the application program, then the finger is removed from the touch screen, the window of the application program is pulled up or pulled down by pulling the scroll bar within another specified time, when the position which the user desires to store is reached, the finger of the user stays at another position (such as another chat record, another short message information and another picture) in the application program for a certain time, and when the finger of the user is removed from the touch screen, the information from the certain position to the another position is selected. Then the transformation module converts the selected information into a picture format in a screenshot mode and executes the following operations: decomposing the image, transforming the image into a horizontal component, a vertical component, a diagonal component, and other components using wavelet transformation, and storing the other components and the diagonal component to a designated area of the electronic device, storing the horizontal component and the vertical component to a remote device; wherein storing to the remote device comprises: inserting a key input by a user between the horizontal component and the vertical component, thereby generating a first data sequence; sending the first data sequence to a remote device such as a cloud server, so that the remote device performs first verification according to the first data sequence and forms a verification code; and receiving the verification code returned by the remote equipment, and storing the verification code in the specified area of the electronic equipment for use in subsequent calling. Therefore, the safety of information in the electronic equipment can be ensured, and the data information can be ensured to be incomplete after the electronic equipment is lost or is cracked, unlocked and entered into the application program by a non-owner, so that the cracked and entered person can not restore the part of data, and the information is ensured not to be leaked; meanwhile, all the contents to be stored for peeping prevention and leakage prevention are not required to be encrypted, so that the data processing efficiency can be effectively improved, and the user experience is improved.
